Anytime the transmission flares like you say, the two speed sensors detect it and put the unit into a 2nd gear only mode, and the key codes can give you PCM codes but not TCM codes in 94, 95 and up yes. You may have either an internal slipping, or a solenoid problem, the shift solenoids are in the black covered solenoid pack, so if one fails you'll find a code. A inexpensive scan tool, will come with a Chrysler cable, and this is step one after a roadtest and fluid and linkage test. You could try a key on, off, on, off, on and see what you get anyway, I hope everything goes ok, and I'm glad to try and help, of course, thank-you for posting a reply and the information.
